--------------------------------------------
Summary: Debian init shadows CASSANDRA_HEAPDUMP_DIR
Key: CASSANDRA-13843
URL: https://issues.apache.org/jira/browse/CASSANDRA-13843
Project: Cassandra
Issue Type: Bug
Components: Observability
Reporter: Andrew Jorgensen
Priority: Minor
The debian init script sets the heap dump file directly using the cassandra
users home directory and the -H flag to the cassandra process[1
title|https://github.com/apache/cassandra/blob/8b3a60b9a7dbefeecc06bace617279612ec7092d/debian/init#L76].
The cassandra heap dump location can also be set in the cassandra-env.sh file
using CASSANDRA_HEAPDUMP_DIR. Unfortunately the debian init heap dump location
is based off the home directory of the cassandra user and cannot easily be
changed. Also unfortunately if you do `ps aux | grep casandra` you can clearly
see that the -H flag takes precedent over the value found in cassandra-env.sh.
This makes it difficult to change the heap dump location for cassandra and is
non-intuitive when the value is set in cassandra-env.sh why the heap dump does
not actually end up in the correct place.
